1) Weight of a single sensor : active + inactive material
The detail of the SFSW volume is below :

Note : SFPI is noted as AIR because it is an assembly of 2 volumes :
The definition of the SSD material is below :
As a result, on the sensor level :
- weight active (Silicon) : 0.00220185 [kg]
- density active = 2.3 g.cm^-3
- weight inactive material : 0.006016 - 0.00220185 = 0.00381415 [kg] ;
- density (average over volumes --> sum(#*density)/#) = 2.78 g.cm^-3 (6*1.8 + 2*8.96 + 12*2.3+4*2*2.7) / 28 = 2.78
